Monitoring, Science, and Data Management Track / Training Workshop: Stormwater Sampling Methodologies: A Primer for All QSPs, QISPs, and Municipal Staff
Short Description: 

Discussion of sampling methodologies and issues that QSPs, QISPs, and municipal staff encounter in programs to remain compliant with the requirements of the CGP, IGP, and Phase I and II MS4 Permits. Where to sample, how to sample, what the lab really needs, and what to submit in SMARTS.

The Training will focus on each of the core storm water related General Permits (construction, Industrial, Phase I and Phase II MS4) sampling requirements and the methodologies to comply with those permits. Each Permit topic will have 30 minutes to discuss the sampling triggers pertinent to that Permit:
• CGP: What are the triggers for a sampling event? Where are the appropriate locations to sample? Examples of projects with situations where sampling should occur and why. What to do if there are NAL exceedances. Non-visible pollutant sampling, will it ever be performed?
• IGP: New considerations for recent IGP Amendments. Considerations for TMDLs and Sufficiently Sensitive Test Methods. When is a storm a qualifying discharge? What constituents have special collection requirements. How to determine an appropriate sampling location. Sampling methodologies: sheet flow, in pipe collection, auto samplers, etc.
• MS4: Collecting a representative sample, the how to on a site-specific basis, and the importance of flow. Discrete (grab) vs. composite samples, time-weighted vs. flow-weighted approaches, and the nuances of flow weighted sampling including different approaches for outfalls and receiving water.
Example photos of how and where to sample based on real world and hypothetical situations will be presented to the attendees to engage in the conversations. Sampling methodologies, best practices, and unique scenarios will be shared and the attendees will be encouraged to share their experiences with challenging sampling issues.
Following the Permit specific sampling requirements, laboratory representatives will have a 25-minute session to discuss lab requirements, typical issues, and discuss how field staff and labs can work together for higher quality results.
SMARTS ad hoc reporting and the appropriate uses and timelines. How the regional and state boards use this data will be discussed along with attendees encouraged to discuss issues they have encountered. (15-20 minutes).
Following the SMARTS discussions, hands on meter and equipment session will conclude the workshop. Targeted activities will litmus paper use/reading, calibrating pH meters, guess the turbidities, match the right lab bottle for the sampled constituents.
